In 1537,
Portugal established a settlement of
Dianga in the area of Chittagong, bringing the Catholic Church and missionaries with them. The first churches were set up in 1600 in a settlement which now forms Dianga and the city of Chittagong.
Jesuit Father Francesco Fernandez, who came to Dianga in 1598, and who was blinded and tortured and died in captivity on November 14, 1602, is
Bengal's first
martyr. In 1845 Chittagong became the seat of the first
Apostolic Vicariate of Eastern Bengal, and later the administration was transferred to
Dhaka. Noakhali was also the first place to have the
Holy Cross missionaries who arrived there in June, 1853. The
Diocese of Chittagong was canonically erected on May 25, 1927, splitting off about half of the territory that then comprised the Diocese of Dhaka. The newly erected bishopric then included Chittagong,
Noakhali,
Barisal,
Gournadi,
Narikelbari,
Haflong,
Badarpur,
Akyab,
Sandoway,
Gyeithaw and
Chaugtha. It was entrusted to the care of the Canadian
Province of the Congregation of Holy Cross. Atypically, its first two Ordinaries remained
Titular bishops, as if merely
Apostolic vicars. Akyab, Sandoway etc. in present
Myanmar were handed over to the
La Salette Fathers in the future
Apostolic Prefecture of Akyab in 1937–38. On 9 July 1940, the Apostolic Prefecture of Akyab (in
Burma (now the Diocese of Pyay) was separated from the Diocese. When the
ecclesiastical province of Dhaka was created in July, 1950, Chittagong became a
suffragan of the new Metropolitan of Dhaka. Later in 1952, portions of the Diocese of Chittagong situated in
Assam (northeast India) were detached to form the
Apostolic Prefecture of Haflong, and later the then
Roman Catholic Diocese of Silchar (now the
Diocese of Agartala) and the
Diocese of Aizawl. On 29 December 2015, the
Diocese of Barisal, now one of its
suffragans, was created from the diocese. On February 2, 2017 the bishopric was elevated by
Pope Francis to metropolitan rank as
Archdiocese of Chittagong, with two suffragans, and on December 28, 2018 was renamed Chattogram. ==Episcopal ordinaries==
